Disadvantages of Using Bluetooth:

Limited range: Bluetooth connections typically become weaker or lost when the devices are more than 10 meters apart. Lower transfer speeds: Bluetooth may have slower data transfer rates than USB or Wi-Fi technologies.

Bluetooth can support up to 7 connections at any one time. The realistic limit depends on the bandwidth requirement of each device. Note that each Bluetooth service can only support one connection at a time.

What does Bluetooth 5.0 mean? Compared to its predecessor, Bluetooth 4.2 Low Energy, Bluetooth 5.0 is twice as fast, has four times the range and can transfer eight times as much data. If you want hard stats, we're talking a bandwidth of 2Mbps.

While Bluetooth 5 allowed streaming audio to two separate devices, version 5.2 allows one-to-many and many-to-one broadcast. This enables multiple Bluetooth audio devices to play audio from a single source, while also allowing multiple sources to simultaneously serve several audio streams to a single receiver.

One factor is Bluetooth is on the 2.4GHz band, and WiFi on that band is many times more powerful - so Bluetooth packets can only get through in the gaps between Wifi transmissions.

Bluetooth is a short-range communication technology standard, which means that paired devices cannot use it if they are far away from each other. Transmission speed. Bluetooth file transfers are slow and the maximum transfer speed is only 6 MB/s. This means a long wait if you need to transfer a larger file.

Longer range: Bluetooth 4.2 can hold connection to another device for a maximum of 60 meters (200 feet). With Bluetooth 5.0, that distance is quadrupled to 240 meters (800 feet).

How far does Bluetooth usually reach? Commercial electronics, including most smartphones, headphones, earbuds, and portable speakers, fall into class 2, which gives them a range of about 33 feet. Bluetooth 5.0 and above strengthen range and quality.

Improved Speed and Range

While the range of Bluetooth has never been too much of an issue, it's always great to get a little bit more room to work with. In version 5.0, the software has four times the range, two times the speed, and eight times the broadcasting capacity of past versions.

The lower the latency, the faster the connection. Latency in modern Bluetooth 5.0 + devices can reach as low as 40ms natively. This means the signal is sent from the device to the receiver in 40 milliseconds or 0.04 seconds. As you can see, "0.04" is a bit clumsy so 40 milliseconds is used instead.

When using frequency-shift keying modulation, the transmission rate of Bluetooth classic is about 1Mbps. The data rate is enhanced up to 24 Mbps in Bluetooth low-energy (BLE).

Bluetooth 5.2, commonly referred to as Bluetooth LE Audio: It is a standard that was released at the beginning of 2020, and it enhances energy efficiency and sound quality in all connected devices used for audio tasks.

Bluetooth 5 allows for broadcasting to two different devices, which essentially means that audio can be sent from a laptop or mobile phone to multiple different rooms within a building. This even allows for sharing music between two distinct pairs of headphones.

This feature improves user experience in cases where multiple applications are running on the same Bluetooth LE stack. It also reduces overall latency. EATT is optional per the specification, and it requires an encrypted connection between both Bluetooth LE devices — making it more secure than ATT.

Bluetooth connection problems are usually caused by the Bluetooth device being paired with another gadget. You also need to be within range, the devices have to be fully charged, they need to use compatible Bluetooth versions, and you need to stay away from Smart Home devices, USB hubs, and Wi-Fi routers.

Bluetooth Issues

Bluetooth interference - Since Bluetooth is a wireless technology, it is susceptible to interference from other devices.

The range of the Bluetooth® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. NOTE: Not all audio devices are supplied with Bluetooth capability.
